Diagrams as code is becoming a popular way to diagram software architecture, particularly for longlived highlevel documentation write the diagram source in a textbased domain specific language (e.g. PlantUML or Mermaid) or a programming language, and render diagrams using webbased or command line tooling. The benefits are well understood writing the diagram source as text allows for easy integration into software development practices and toolchains, plus the automatic layout facilities allow authors to focus on content. The problem with this approach is that it's easy for diagrams to get out of sync. Enter "diagrams as code 2.0" and the open source Structurizr DSL a Javabased library providing a way to define a model of our software architecture and the views that we'd like to see, ultimately resulting in a consistent set of diagrams that are generated for us.

Lecture took place on Wednesday, 22nd June at 10:30 in Room 3

He is also the creator of the C4 model for visualising software architecture, and the founder of Structurizr. Simon is a regular speaker at international software development conferences, and travels the world to help organisations visualise and document their software architecture.
